Methods and systems for providing electricity according to power policy

摘要

The methods and systems are provided to adaptively change power threshold at a policy based power supply device (PBPSD). The PBPSD (101) retrieves a first power policy and determines a power threshold substantially based on the first power policy. A power port authority is also determined based on the first power policy. The PBPSD (101) then provides power to each of the plurality of power ports based on the power threshold and the power port priority. The PBPSD (101) comprises a first processor, a plurality of power connectors, and a plurality of AC-DC regulators. Each of the plurality of power connectors is capable of receiving electricity from a power supply.
